On a street with 80 houses, three students with paper routes deliver 35 Toronto stars,46 Globe and mails and 26 Toronto Sun. A house may receive no papers, one paper or two paper. No houses receives all three, and no house receives more then one copy of the same newspaper. What is the smallest number of houses that could have two papers delivered? What is the greatest number of houses that could have two papers delivered?

squares, rhombus, rectangles

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
